I' Applicatin nlea March 30, 1927'.vr v serial ism-179,473.

This invention relates to a means forsup-f `-plying fresh air, either heated or'ofnormal atmospheric temperatures, to closed areas'` and for simultaneously removing impureair l 5 from said closed areas whereby a circulation of fresh air and thorough ventilation of such closed areas vmay be' continuously'ef-v fected. w

V*The invention relates particularly to an improvement'in that type of heating appara-v tus'more specifically disclosed, explained and -fclaimed in my co-pending application for l patent filed September 9,1925, Serial Numfb'eraaee. In contradistinction to the heater disclosed l in said application, which isl aheating unitV or'an individual or single area, this inven i. tion rrelatesto a apparatus for heating and Ventilating a number of vclosed` areas'or fory ,'20`supp1ying Jfresh heated air at a number'offf 'places in a singlearea Wherethe''sizeof` vsame makes this necessary, and the object-ot this invention is to provide asimple andv vcompact apparatus which Will constitute a; central heating unit for a number `'of closed lareas or spaces; inwhich 'aV gaseous fuel is` arrange'd'to beused; to provide apparatus,

- 'of this character in Which-no fumes or gases can escape into' the closed area-or areasyand "V to provide la heating apparatus by which -pure fresh air may be delivered into and circulated in rooms or yother enclosures and heated to a degree thatvvilll provide a comfortable atmosphere Without over heating or A drying. f y l Other objects of the invention will appear from the specication :tollowinginconn'ection With the accompanying drawings, Which illustrate a practical and convenient form '4U of embodiment of the invention and in Which Fig; 1 is afsectional velevation o-aheating unit embodying the invention.`

-A Fig. 2 is a horizontal section on line 2'-1-2', Fig, v1,- and v f n ,Y Fignf is a top plan viewgshowin'g'an arrangement Vof the fresh air inlet pipe, the heated Vair conveying pipes, and the used or impure airlreturn pipes. j

The invention Aconsists of an 'apparatus be readily eiected. f Y

for heating the outside air,ic`onveying the' 50 heated air to "a number' 0i" closed but lseparate `areas or rooms,vWhichv-may be'located'.

on dierent oors of a building, and for `re- ,moving the used or impure air lfromthel v areas .or lrooms byV returning it to'theap'- v55 Y paratus and from there causing its eXit,'With the iueV gases-to 'the'outside air. The. ap-

-paratus is arranged at 'aV-most convenient y centralpoint from WhichA the distribution of t-he heated air and the Withdrawal romthe closed areas of the stale or vitiated'zair'may In 'the' formy of 'embodiment the invene tionjshovvn-'in thedravvingdl indicates a i "heatingvchamberf, Which for-convenience and cheapness of manufacture Vis of cylindrical shape, and vis preferably cone shaped atpthe top. -Theheating-'chamber lf-.is in direct communication With the" atmosphere, preferablythrough the medium of. a conduit 2 70 k through Whichthe outside air may enterintothe heatingjchamber `1. v

'freely s `:Su'it'ably supported Within the; heating chamber 1, and spaced from the Walls therechris a ring chamber' in VWhich is disposed 75 ajburner 4, supplied with a gaseous fuel from a suitable source,`through pipep. `The hot gases of combustion are conveyed from j said rin-'gv chamber 3 *upwardlythrough a plurality of pipes '6,' Which at theirupper ,.80-

vends 'are in 'communication Withthexenlargedportion 7, of a stack 8 centrally disposed Within and extending to near the bottom of said v`heating chamber. 1,- thev stack 8 n being closed atth'e bottoni- By means of 85 said stack 8 the combustion-gases' enteringl said enlarged portion .7fof the combustion ring chamber-3`- throughthe interconnecting pipes 6, arelled tothe outside. The j 'outside' air 1 inflowing 'through conduit 2A 90 into the heating chamberl, is heated by contact vWith' the combustion,r'iiig-A chamber v3- Vand the pipes- 6k connected there'vvith'and, f.

When so heated, is led offV from'the `chamber A 1,i through a'plurality 'of flues 9 into areas g5' to be heated, through means 'disposed insaid areas and Which-meansmay comprise-v'reg-y `isters 10 'as shown having heated' air Y and usled'or stale air exits l0, or any if Y other devices or arrangement by Which the heated fresh air may enter closed areas and `the used or stale heated air may be `removed from the closed areas continuously. The

stale or usedy heated air, under the stack energy, is removed from the .closed 'areas through fthe register `exits t 1 0, throughV fines 11, which connect directly anducommunicate With the stack 8v nearthe bottoml l closed end'thereof "and,` as seenv in' Fig.' 1',

f seen .in Fig.` l, ythe lower part of the stack 8extends through and belowthe ring cham- V- below the point of entrance thereinto of the,

gases of combustion from the ringV chamber 3, whereby-the stale or :used =air isremoved; fromy closed areas by the stack draft. As

Vber-3 and isspaced therefrom to allow ,free

vcirculation thereabout of theincoming out side air., Thegdispositionfofjtheq stack 8 throughthis ringfchamber exposes :the .stack to thefheat ofthecombustionlchamber 3,-'.

whereby the stack temperatureis `augmented and the stack energy increased. In opera-,iY tion, the outside air enters the chambervl,

l and after being heated by passing over and ,in contact withl thering chamber 3V and the pipes 6, is conveyed through flues I9 into the areas to be 'heated-,through the inlet openings l0" of thedevices -10 disposed 'inxsuch' areas. Y Simultaneously Withftheentry kof `the lheated air intothe areas, Vsubstantially an` Y `equivalent quantityof the air in such areas is continuously vvithdrawn therefrom by the :stack draft, such air leaving the yareas e through the openings 10" in the jdevices 10,
